PICKET-MILL.

SPECIFICATION forming part of Letters Patent No. 509,405, dated November28, 1893.

Applicationiiled June 19,1893.

To all whom it may concern.-

Beit known that we, FREEMAN W. STROH, MILTON J MoINTosH, and JOHN S.McINTosH, citizens of the United States, residing at Massillon, in thecounty of Stark and State of Ohio, have invented certain new and usefulImprovements in Picket-Mills; and We do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the annexed drawings, making a part of this specification,and to 1etters of reference marked thereon, in which- Figure l, is aperspective View. Fig. 2 is a view, showing portions of the feed rolls,and illustrating one of the roll adjusting brackets and eccentrics, andshaft. Fig. 3, is a longitudinal section of the mill. Fig. 4, is a topview, of the upper feed rolls and illustrating a portion of the gang sawshaft. Fig. 5, is a modified form of tension for the feed rolls.

The present invention has relation to picket mills and it consists inthe different parts hereinafter described, and particularly pointed outin the claims.

Similar let-ters of reference indicate corre- .sponding parts in all thefigures of the drawings.

In the accompanying drawings A represents the frame which may besubstantially of the form shown or it may be of any other desired form,reference being had to properly attaching the dierent parts.

To the top or upper rails d of the frame A is journaled the gang sawshaft B, which shaft is provided with any desired number of saws such asb. For the purpose of journaling the lower feed rolls c the groovedlianges CZ are provided, and are located substantially as illustrated inFigs. l and 2. The upper feed rolls C are journaled to the top or upperends of the bars D, which bars extend downward through the hollow postsE, as illustrated in Figs. l and 2. The bottom orloWer ends of the barsD are provided with the screw threaded nuts c which are for the purposehereinafter described. To the sides of the frame A are located theadjustable brackets F, which brackets are provided at their bottom orlower ends with the flanges or ribs e, between which Iianges or ribs arelocated the eccentrics G said eccentrics being SerialNo. 478,050. (Nomodel.)

securely attached in any convenient and Well known manner to the shaftH, said shaft being properly journaled to the frame A. The eccentricsare for the purpose of elevating and lowering the brackets F, and at thesame time adjusting the space between the upper and lower feed rollscandC. The object and purpose of providing a means for adJ usting the upperfeed rolls independent of the tension of said upper feed rolls is toprovide for sawing timber of different thickness into pickets or strips.For the purpose of setting the brackets F and holding them at anydesired point of adjustment the lever I is provided, which lever isprovided with the flange J, said flange being provided with a series ofapertures such as f, said apertures being for the purpose of receivingthe pin g. For the purpose of holding the pin g an aperture is formed inthe post kof the frame A. For the purpose of providing a tension for theupper feed rolls, the springs 7i are provided, which springs are locatedaround the bars D, and between the nuts c and the flanges h said flangesbeing preferably formed integral With the brackets F, and for thepurpose of causing the bars D to follow the movements of the brackets Fas they are moved up and down, the bars D are attached tothe flanges hor their equivalents, thereby giving to the springs 7i. the same tensionat all points of adjustment of the brackets F. To the top of the frame Ais attached the feed table K which table is constructed in the ordinarymanner. The rear or delivery table L is inclined upward from its innerend and is so located for the purpose of permit ting the inner ends ofthe pickets or strips to drop below the rear feed rolls. For the purposeof communicating rotary motion to the top or upper feed rolls a beltsuch as M leads from the gang-saw shaft B to the wheel N, which wheel issecured to the shaft N', and to the opposite end of said shaftisattached the sprocket wheel N11 from which the sprocket chain N 2leads and communicates rotary motion to the sprocket wheel'Ns which inturn communicates rotary motion to the sprocket wheel N4 by means of theshaft N5. From the Wheel N4 leadsthe sprocket chain N6, whichcommunicates rotary motion to the IOO two upper feed rolls by means ofthe wheels N7, N8, and N9, and the sprocket chain N10. It will beunderstood that by our manner of communicating rotary motion to theupper feed rolls they can be adjusted up and down Without interferingwith the tension of the different sprocket chains and belting. Upon thegang-saw shaft B are located a number of collars Z which are for thepurpose of spacing the saws b'. For the purpose of providing a means forremoving, the collars Z and the saws b the shaft B is formed somewhatshorter than the frame P as illustrated in Fig. 4. It will be understoodthat by this arrangement the box P can be removed and slid or slippedfrom the end of the shaft B without removing said box from off its frameand Without disturbing in any manner the gang-saws, shaft B.

In Fig. 5 we have illustrated a modified form for providing a tensionfor the upper feed rolls, which modification consists in pro. viding thepivoted arms R, which arms are provided with the weights R. The arms Rare held in operative position by means of the clevises 7c located uponthe lower ends of the bars D. The inclined table L extends under thefeed table K as shown in Fig. 3, and the shaft N located above saidinclined table so that as the sawed strips fall upon said shaft theywill be carried down the inclined table and in reach of the personfeeding the gang saws so as to be removed.

Having fully described our invention, what We claim as new, and desireto secure by Letters Patent, is-

1. The combination of the frame A, the gang-saw shaft B, provided withsaws such as b, the feed rolls c and C, the bars D having journaled totheir top or upper ends the upper feed rolls, the hollow posts E, theadjustable brackets F carrying the bars D, and the upper feed rolls andprovided with the ribs e, the eccentrics G located upon the shaft H, thelever I, and means for holding` said lever, substantially as and for thepurpose specified.

2. The combination of the frame A, the gang-saw shaft B provided withsaws such as b, the feed rolls o and C and means for communicatingrotary motion to the rolls C, the bars D, carrying the upper rolls, thebrackets F carrying the bars D, the springs h, the cccentrics Glocatedupon the shaft H, the lever I, and means for holding the lever, thetableK, and the inclined table L, substantially as and for thepurposeset forth.

In testimony that We claim the above we have hereunto subscribed ournames in the presence of two witnesses.
